Remington 5 1\2 small Pistol Primer

Within every Kleanbore primer is a group of subcomponents assembled to exceptionally precise tolerances. Primer cup dimensions are controlled to four decimal places. The priming mix is specially formulated for consistent ignition with a wide variety of powder types, and tested for reliability over a temperature range of -20°F to +150°F. Individual primer pellet weight is controlled to .01 grams. A unique tripod anvil design creates a larger "sweet spot" with maximum sensitivity - even with off-center firing pin strikes. And lastly, each lot is 100% visually inspected and subjected to critical ballistic tests. 100 per box.
